Be it known that I, TIMOTHY STEBBINs, a citizen of the United States of America, and resident of Davenport, county of Scott, State of Iowa, have invented a.y certain new and useful Improvement in Pumps, of which the following is a specification.

My invention relates to pumps of the type usually employed for raising water from driven or cased wells, and is directed more especially to double-acting force pumps, and its principal object is the providing of a system of drainage and a method of packing, whereby, with the casing terminating at the ground level, the water cannot risc above or remain above the frost line except during the :interval of pumping, and is yet capable of being discharged with full force at the Outlet on the first or second stroke of the pump rod, the pump thereby being rendered frost-proof although quick acting. Another object .is to provide a construction wherein the casing terminates at the ground l'evelV thus avoiding the necessity of digging a pitV to the frost line, an operation often times expensive and laborious, especially in rock formation. Still another object is to provide a construction wherein the employment of the usual stuffing-box about the pump rod is avoided, thus contributing to the light ruiming of the pump by removing unnecessary friction. Another object is to provide means whereby the pump rod is maintained in perfect alinement, insuring against binding. And yet another object is to pro-vide a construction wherein any of the working parts or parts subject to wear, or any of the packings can be readily removed and renewed without taking up the pump or removing the pipe, or cylinder from the well.

With these objects in view, my invention consists of certain novel features of construction hereinafter described and shown in the accompanying drawings, in which Figure l, is a side elevation of a pump of the double acting type to which my improvements have been applied. Fig. 2, is a vertical cross section of the pump showingk my improvements in place. Fig. 3, is a top plan view ofthe pump base. Fig. 4, is a top plan view of the base cap. Fig. 5, is a top plan view of a special combined connecting and packing T usedl in'my device. Fig. 6, isa side elevation o fa double couplingand packing member. Figi'. 7 is a horizontal crossonce section thereof taken on line 7---7V of Fig. 6. Fig. 8, is a side elevation of a lower pump cylinder partly in section, Fig. 9, is a side elevation of a pump head, "and Fig. l0, is a lSide view of a detail of the pump head.

ln the drawings, in which similar refer- V'characters refer to similar parts throughout the several views, I have illustrated' the preferred embodiment of my invention and show same as consisting of the base 12 which is provided with the interior compartments 13 and 14, communicating with each other through the port l5. Screw threaded into suitable openings in the upper wall of coinpartment 13, is the discharge pipe lo, equipped with the spout 17, and also the pipe 18, forming the air chamber and also functioning as a pedestal for the pump head 19. This pump head is provided Iwith the sockets 20, at its upper end and 2l, at the lower, which are adapted to receive the guides 22, and 23. These guides consist of the body portion 24, and the rounded shank 25, extending at right `angles thereto. The

.body portion is provided with a rectangular opening adapted to slidably engage the iat bai' extension 26a, of the pump rod 26. With the rounded Shanks 25, in the sockets 22, and '23, and with the pump rod centrally suspended with respect to the pump base, these guides are rigidly secured to place bythe rset screw 27. These two guides alined with without binding.

The pump handle 29, may be pivotally secured' to the pump head as at 3Q/through the medium of the fulcrum 3l, and pivotally secured to the flat bar extension' to the pumprod 26, as at 32. This fiat bar 26 may also vfunction as a connectionV of the pump-rod to a wind-mill or other source of power. When the rod is being operated by power the handle may he disconnected by removing pin The free and easy reciprocation of the pump-rod in its bearings is further' insured .by the brace 34, which securely maintains the guides 22, and 23, in alinement with the opening in the base-cap plug 28.

Screw threaded into the lower portion 35, of the base l2, is the extension casing 36, the length of which is determined by the depth of the frost zone, which naturally varies in lili different climates, the purpose being, to have it of a length that will bring its lower end well below the frost line. Screw threaded to the lower end thereof is the combined reducing coupling and packing retaining ring 37, which connects the extension 36, to the well casing proper 38, which may be of slightly reduced diameter and which is of a length as determined by the depth of the well, which may be a hundred or more feet deep. To the lower end of the casing 38, the lower cylinder 39, is secured, and to the lower end of this cylinder provision is made for the securing thereto of the usual. suction pipe and strainer (not shown).

The pump-rod 26, passes loosely through the base-cap plug 28, and is secured to the plunger 40, arranged for reciprocation in theupper cylinder 41. This portion of the pump-rod extending from the Hat bar 26a to the plunger 40, is made of pipe. From the underside of the plunger 40, it extends in jointed sections of convenient length to the plunger 42, in the lower cylinder 39, to which it is securely united. This portion of the rod is made of wood, its natural buoyancy contributing to the ease of operating the pump.

In a double acting pump, the water is sucked into the lower cylinder on the upstroke of the plunger only, and to insure a steady, solid stream of considerable force at the spout or outlet, the upper cylinder 41, is made of a capacity only one-half that of the lower cylinder. On the up-stroke, half of the water is discharged from the spout and the other half passes into the upper cylinder. Then on the down-stroke the upper plunger forces the Water out of this cylinder through the spout, thus maintaining a solid, steady stream.

Centrally located within the chamber 14, of the base 12, is the T casting 42, with the barrel of the T extending vertically and the branch horizontally. This T is rigidly held centrally of the chamber 14, by forcing the outer end of the branch portion of the T solidly against the face of the port 15, through the medium of the set screw 43, tapped into the wall of the chamber 14, at a point diametrically opposite the port 15. The back of the Vertical barrel of the T being provided with the counter sunk lug 44, forming a seat for the end of the set screw.

By inserting a ring packing 45, between the flange 46, and the face of the port 15, a water tight joint is effected between the T casting and the chamber 13, by screwing the set screw 43, solidly against the lug 44. This also rigidly secures the T casting in proper position withinthe chamber 14. Slidably connected to the lower opening of the T, by the packing gland 47, which has a threaded engagement with the outer surface of the lower end of the T, is the water pipe 48.

This pipe has a screw threaded connection at its lower end with a special shaped double connection 49. This special connection consists ofy the outer .barrel 50, and the inner barrel 51, the two being connected at their center of length by the conduits 52-52, affording communication from the interior of the inner barrel 51, to the exterior of the outer barrel 50. Near the lower end of the barrel 50 and exteriorly thereof, is the annular flange 51a, for engagement with the ring packing 51, seated on the flange 51, formed interiorly of the reducing connection 37.

Screw threaded into the upper end oi the inner barrel 51, is the connection or spreader pipe 53, which passes through the waterpipe 43, and is centrally located with respect thereto and is of such external diameter as to leave an annular chamber or space between its external face and the interior of the water pipe for the free passage of a 'thin sheet of water. lts upper end passes ou through the T casting 42, with the upper end of which, it has a slidable water tight engagement through the medium of the packing gland or stulling box 5l. The upper end of this pipe terminates in the enlarged head 55, seated within a recess formed in the under side of the base-cap plug 28.

Extending upwardly from the upper edge of the chamber 14, are the three hook shaped lugs 56. The chamber 14, is closed by the base-cap 57, which is securely locked in position by turning the three lugs 58, under the hooked lugs 56. It is provided with the central opening 59, into which the plug 28, is screwed. `With the cap securely locked to the base and the plug contacting the end of pipe 53, the pipe will be forced downwardly on screwing the plug into the cap, causing the packing ring 51a, to seat firmly against the packing 51h. The upper cylinder 41, is secured in proper position by the reducing coupling 60, which is screw threaded to the pipe 61, which in turn is threaded to the lower end of the inner barrel 51. Tt will be observed that the pump-rod 26, is loosely suspended from the pump handle or wind-mill gearing for free Vertical reciprocation, unimpeded by friction arising from packing glands or stuffing boxes at any point in its length.

In operation, the casing 38, is iilled with water at all times, and on each up-stroke of the pump rod, one half of the water raised by the lower cylinder 39, passes into the upper cylinder 41, and the other half passes around the outside of connection 60, through the special connection 49, by passing around the outside of the inner barrel 51, and through the water pipe 48, in a thin sheet on the outside of the connecting pipe 53, into the T casting 42, and out of the horizontally extending branch, through the port 15, into the chamber 13, and from thence through the discharge pipe 16, out through the spout 17.

On the down stroke, the plunger' 40, forces the water out of cylinder 41, on out to the discharge spout, thus maintaining a solid steady stream at the spout. When the operation of pumping ceases, all the water standing in the discharge pipe 16, chamber 13, T casting 42, water pipe 48, and special connection i-9, immediately flows back out of the frost vent 62, thus thoroughly draining the entire pump to a point below the frost line, preventing freezing.

As the body'of water from the vent 62, out to the discharge spout is in the form of a thin circular sheet of a volume as delined by the space between the outer surface of the connecting pipe 53, and the interior surface of the water pipe 4S, no more than one upward stroke of the pump will be required to raise the water to the point of discharge, regardless of the depth of the well. An exceedingly quick acting pump is thus produced.

If water happened to seep past the plunger 4:0, which is likely on the wearing of the leather packing, instead of this water following along the pump-rod 26, filling the connecting pipe 53, and freezingthe pu1np-rod solidly therein, this seepage will pass up through pipe 61, into the inner barrel 51, of the special connection 49, and out of the conduits 52, into the reducer 37, from which it will pass out through the opening 63, provided for the purpose. It is thus to .be seen that no water can remain in the pump above the frost line, when the pump is not in operation. i

The lower cylinder consists of the body or barrel 39, provided with the brass lining 64;. Screw threaded to the lower end of the cylinder is the cylinder cap 65, which is provided with the valve seat 66. le'eated thereon is the check valve 67, provided with the four depending lugs 68, the inner faces of which are recessed to receive the free ends of the two looped spring wires 69, which cross each other at right angles and have the form of half of an ellipse. When the valve is on its seat, these wires extend entirely below the seat and are free to expand a distance somewhat greater than the interl'ial diameter of the seat, but upon a slight upward pull, they will contract sutiiciently to pass through the seat, thus permitting the valve to be raised slightly from the seat or be removed entirely. Extending upwardly from the valve is the threaded shank 70. lThe lplunger consists of the cage 71, and the usual leathers 72. The

lower end of the cage is provided with the yoke member 73, having a threaded opening 74, in alinement with the threaded shank 70, of the check valve. Inside of the cage 71, the puppet valve 75, provided with 'the vertical leg 76, is arranged for free vertical reciprocation, whereby it will seat on a seat provided in the cage on the up-stroke and lift off the seat on the down stroke.

@ne of the principal features in the design of the pump is the relative size, arrangement and connection of parts whereby the entire internal mechanism can be readily removed and replaced with very little effort and with the aid of an ordinary monkey wrench only. To remove the parts for renewing the packing, replacing worn leathers or making other repairs, the handle 29, is detached and the pump bar guides 22, and 23, are removed from their sockets 20, and 21. The base cap plufr 28, is then unscrewed and the base cap 55, turned out of engagement with the lugs 56.

The pump-rod 26 is then pushed down until the plunger 71, in the lower cylinder strikes the valve 67, then by turning same to the right it will screw onto the threaded shank 70, and as this shank passes through the threaded opening' 74, and contacts the end of the puppet valve leg 76, the valve will be forced off its seat and the entire body of water in the pump will rest on the lower valve 67. Then by slightly lifting the pump-rod the valve will be raised its seat, permitting the water to rush back into the well, washing off the valves, removing any sediment that may have settled on them and avoiding the necessity of lifting the entire body of water contained in the pump when bringing the valves to the surface.

After the water has drained out, a slight upward jerk on the pump-rod, the lower valve will be pulled off its seat, the wire springs 69, compressing sufficiently to pass through the seat. Then upon removing the set screw 43, which holds all the remaining parts in suspension, the rod and all the mside parts can be drawn up.
